Section 1: INTRODUCTION
The OGDEN ETR-9040 limit control is an over tempera-
ture protection or a high limit safety device with a
latching output. The limit removes power in an abnor-
mal condition when the process temperature is higher
than the high limit set point or lower than the low limit
set point.
The unit is powered by an 11-26 or 90-264VDC/VAC
supply, incorporating a 3 amp form C relay for limit
control. The universal input is fully programmable for
PT100, thermocouple types J, K, T, E, B, R, S, N, L and
0~60mV, without the need to modify the unit. The ETR-
9040 has an optional port available for one of the fol-
lowing functions: alarm output, RS-485 communica-
tions, DC power supply output, limit annunciator output
or event input. Alternative control output options also
include SSR drive and triac. The input signal is digi-
tized by using an 18-bit A to D converter. Its fast sam-
pling rate
(5 times/second) allows the ETR-9040 to control fast
processes such as pressure and flow.
Digital communication RS-485 is available as an addi-
tional option. This option allows the ETR-9040 to be
integrated with a supervisory control system. As a
alternative option, alarm functions and alarm modes
can also be programmed for a specific application. The
DC power supply output option can be used to power
an external sensor or transmitter. The event input
option can be programmed to reset or lock the con-
troller from a remote switch. The limit annunciator
option can be used to control an alarm buzzer
Three methods can be used to program the ETR-9040
1. Use keys on front panel to program the unit manu-
ally.
2. Use a PC and setup software to program the unit
via RS-485 port.
3. Use the P11A, a hand-held programmer to pro-
gram the unit via the programming port.
High accuracy, maximum flexibility, fast response and
user friendly are the main features of the ETR-9040

Section 2: INSTALLATION
RISK OF ELECTRIC SHOCK - Dangerous and poten-
tially fatal voltages are present when working on this
equipment. Before installation or beginning any
troubleshooting procedures, the electric power to this
equipment must be disconnected and locked out as
described by OSHA Standards. Units suspected of
being faulty must be removed and returned to Ogden for
inspection and/or repair. They contain no user servicea-
ble components.
To help minimize the possibility of fire or shock hazards,
do not expose this instrument to rain or excessive
moisture. This control is not to be used in hazardous
locations as defined in Articles 500 and 505 of the
National Electric Code.
Do not use this instrument in areas subject to
hazardous conditions such as excessive shock,
vibration, dirt, moisture, corrosive gases or oil. The
ambient temperature of the areas should not exceed
the maximum rating specified in Section 3, on previous
page.
Unpacking:
Upon receipt of the shipment remove the instrument
from the carton and inspect the unit for shipping dam-
age. If any damage due to transit is noticed, report and
file a claim with the carrier. Write down the model num-
ber, serial number, and date code for future reference
when corresponding with our service center. The serial
number (S/N) and date code (D/C) are located inside
the control.
Mounting:
Make panel cutout to dimensions shown below. Insert
the controller into the panel cutout. The maximum
panel thickness is 1⁄8" (3mm).

Wiring Precautions:
•Before wiring, verify the label for correct model num-
ber and options. Switch off the power when checking.
•Care must be taken to ensure that maximum voltage
ratings specified in Section 3 on previous page are
not exceeded.
•It is recommended that power to these instruments
be protected by fuses and circuit breakers rated at
the minimum value possible.
•All units should be installed inside a suitably ground-
ed metal enclosure to prevent live parts being acces-
sible to human hands and metal tools.
•All wiring must conform to appropriate standards of
good practice, national and local codes and regula-
tions. Wiring must be suitable for the maximum volt-
age, current, and temperature ratings expected in the
system.
•Both solderless terminals or “stripped”leads as
specified in Figure 4.2 below can be used for power
leads. Only “stripped”leads should be used for ther-
mocouple connections to prevent compensation and
resistance errors.
•Take care not to over-tighten the terminal screws.
•Unused control terminals should not be used as
jumper points as they may be internally connected,
causing damage to the unit.
•Verify that the ratings of the output devices and the
inputs as specified in Table 4.2 on Page 8 are not
exceeded.
•Electric power in industrial environments contains a
certain amount of noise in the form of transient volt-
ages and spikes. This electrical noise can enter and
adversely affect the operation of microprocessor-
based controls. For this reason we strongly recom-
mend the use of shielded thermocouple extension
wire which connects from the sensor to the controller.
This wire is a twisted-pair construction with foil wrap
and drain wire. The drain wire is to be attached to
earth ground at the control end only. We carry both
type J and type K in our stock.
NOTE: The use of motor starters in place of magnetic
contactors should be avoided. They have very large
inductive loads that can damage the controller’s relay.
!

Power Wiring:
Connect terminals as shown below in Fig. 4.3. The
ETR-9040 is equipped to operate at either 11-26VAC/VDC
or 90-264VAC. Check that the installation voltage corre-
Input Wiring:
Connect appropriate sensors to terminals 3, 4, or 5 as
illustrated in Figure 4.3 above. Verify that the instru-
ment is selected for the correct sensor and the correct
polarity is observed at both the sensor-end and instru-
ment-end of the cable. Do not run sensor cables in the
same conduit or wiring trough as power lines because
the low level signal is noise sensitive.
When wiring the thermocouple, check the thermocouple
and extension wire (compensating cable) to make sure
they conform to the appropriate thermocouple type
specified by the instrument. Extension wires must be
the same alloy and polarity as the thermocouple. The
total lead resistance should not exceed 100 ohms for
accurate measurements. One hundred ohms of lead
resistance will introduce a 1°F (0.5°C ) error.
For wiring 3 wire RTD (Resistance Temperature
Detector) all leads connecting the RTD to the controller
must be the same gauge and material. If the RTD is a
3 wire device, install the two common wires of the RTD
to terminals 4 and 5. If a 2 wire RTD is to be used,
install a jumper between terminals 4 and 5.

Output Wiring:
Four different types of output devices can be used from
output one. Relay, current, voltage and pulsed voltage
provide a variety of control applications, Verify that the
output device is correctly selected to meet your
application requirements and make certain the ratings
of the output devices are not exceeded before wiring
the system.
The external connections depend on what type of
output is installed. Pulsed voltage output is not isolat-
ed from the internal circuits of the instrument.
Alarm
This instrument offers 14 different alarm modes. Each
one can be selected by pressing the keypads on the
front panel. The detailed descriptions are shown on
Table 5.1, Page 13 and on Tables 5.6 and 5.7, Page
17.
Sensor Placement
Proper sensor placement can eliminate many problems
in a control system. The probe should be placed so
that it can detect any temperature change with minimal
thermal lag. In a process that requires fairly constant
heat output, the probe should be placed close to the
heater. In processes where the heat demand is
variable, the probe should be closer to the work area.
Some experimenting with probe location is often
required to find this optimum position.
In a liquid process, addition of a stirrer will help to
eliminate thermal lag. Since the thermocouple is
basically a point measuring device, placing more than
one thermocouple in parallel will provide an average
temperature reading and produce better results in most
air heated processes.
Proper sensor type is also a very important factor in
obtaining precise measurements. The sensor must
have the correct temperature range to meet the
process requirements. In special processes the sensor
might have to have different requirements such as
leak-proof, anti-vibration, antiseptic, etc.
Standard sensor limits of error are ± 4 degrees F (±2
degrees C) or 0.75% of sensed temperature (half that
for special) plus drift caused by improper protection or
over-temperature occurance. This error is far greater
than controller error and cannot be corrected at the
sensor except by proper selection and replacement.

PV Shift
In certain applications it is desirable to shift the indicated
value from its actual value. This can be easily accom-
plished by using the PV shift function.
Cycle the unit to the SHIF parameter by using the scroll
key. The number you adjust here, either positive or nega-
tive, will be added to the actual value. The SHIF function
will alter PV.
SHIF: PV shift (offset) value
Digital Filter
In certain applications the process value is too unstable
to be read. To improve this, a programmable low pass fil-
ter incorporated in the ETR-9040 can be used. This is a
first order filter with a time constant specified by the FILT
parameter which is contained in the set up menu. The
FILT is defaulted to 0.5 seconds before shipping. Adjust
FILT to change the time constant from 0 to 60 seconds. 0
second represents no filter is applied to the input signal.
The filter is characterized by the following diagram.
Figure 5.1
Filter Characteristics

Display Mode
The DISP in the set up menu is used to select the dis-
play format under normal conditions. If PV is selected,
the display will indicate the process value. If SP1 is
selected, the display will indicate HSP1 value for high
limit control (OUT1 = HI) and high/low limit control
(OUT = HI.LO) or indicate LSP1 value for low limit con-
trol (OUT1 - LO). If SAFE is selected, the display will
indicate the word SAFE for he normal condition.
However, the display will indicate the process value if
the process value goes beyond high limit or low limit. If
an error condition occurs, the display will indicate the
error symbol.
Normal Display
During normal operation, the unit can be configured to
display the process value, high limit or low limit set
point (HSP1 or LSP1 dependent on OUT1 selection) or
the word SAFE.
Abnormal Display
Whenever the process is outside the normal range, the
process value will be displayed.

Reference Data
The are three different types of reference data con-
tained in the set up menu. The reference data is read-
only data. The maximum historical PV, displayed
by , which shows the maximum process value
since the last UNLOCK operation. The minimum histori-
cal PV, displayed by , which shows the minimum
process value since the last UNLOCK operation. The
abnormal time, displayed by , which shows the
total accumulated time (in minutes) that a process has
been in an abnormal condition since the last UNLOCK
operation.
The reference data values will be initiated as soon as
the RESET key is pressed for 4 seconds (UNLOCK
operation). After the UNLOCK operation, the PV.HI and
PV.LO values will start from the current process value
and the T.ABN value will start from zero.
Process Input
INPT: Selects the sensor type and signal type for
the process input.
UNIT: Selects the process unit.
RESO: Selects the location of the decimal point
(Resolution) for most (not all) process related
parameters.
IN.LO: Selects the low scale value for the linear type
input
Hidden If: T/C or RTD type is selected for
INPT.
IN.HI: Selects the high scale value for the linear
type input.
Hidden If: T/C or RTD type is selected.
How to use IN.LO and IN.HI:
If 4-20mA is selected for INPT, let SL specify the
input signal low (i.e., 20mA), S specifies the current
input signal value, the conversion curve of the
process value is shown as follows:
Process Value
Figure 5.2
Conversion Curve for
Linear Type Process
Value
Formula: PV = IN.LO + (IN.HI - IN.LO)
EXAMPLE: A4-20mA current loop pressure transducer
with range 0 - 15kg/c2m is connected to input, then per-
form the following set up:
INPT + 4-20MA IN.LO = 0.0
UNIT = PU IN.LO = 15.0
RESO - 1-DP
Of course, you may select another value for RESO to
alter the resolution.

SH-SL

High Limit Operation
If Hi. is selected for OUT1, the unit will
perform high limit control. When power
is applied, the OUT1 relay is de-ener-
gized. After the 6.5 second self-test
period if the process is below the high
limit set point (HSP1), the output 1 relay
will be energized and the OP1 indicator
will go off. If the process goes above
the high limit set point, the relay will be
de-energized, the OP1 indicator will go
on and the display will show the
process value. After the process falls
below the high limit set point and the
RESET key is pressed or the remote
reset input is applied, the relay will be
energized and the OP1 indicator will go
off.
Limit Control Operation
Low Limit Operation
If Lo is selected for OUT1, the unit will
perform low limit control. When power is
applied, the OUT1 relay is de-energized.
After the 6.5 second self-test period, if
the process is above the low limit set
point (LSP1), the output 1 relay will be
energized and OP1 indicator will go off.
If the process goes below the low limit
set point, the relay will be de-energized,
the OP1 indicator will go on and the dis-
play will show the process value. After
the process rises above the low limit set
point and the RESET key is pressed or
the remote reset input is applied, the
relay will be energized and the OP1 indi-
cator will go off.
High/Low Limit Operation
If Hi.Lo is selected for OUT1, the unit
will perform high/low limit control. When
power is applied, the OUT1 relay is de-
energized. After the 6.5 second self-test
period, if the process is below the high
limit set point (HSP1), and above the low
limit set point (LSP1), the output 1 relay
will be energized and OP1 indicator will
go off. If the process goes above the
high limit set point or below the low limit
set point, the relay will be de-energized,
the OP1 indicator will go on and the dis-
play will show the process value. After
the process is within the normal opera-
tion range, and the RESET key is
pressed or the remote reset input is
applied, the relay will be energized and
the OP1 indicator will go off.

Process Alarms
The output 2 will perform process alarm functions by
selecting ALM for OUT2 and PV.H.A or PV.L.A for AL.FN.
If PV.H.A is selected, the alarm will perform process high
alarm. If PV.L.A is selected, the alarm will perform
process low alarm. The process alarm sets an absolute
trigger level. When the process exceeds that absolute
trigger level, an alarm occurs. The taller level is deter-
mined by SP2 (Set point 1 value) and AL.HY (Alarm hys-
teresis value). The hysteresis value is introduced to avoid
interference action of alarm in a noisy environment.
Normally AL.HY can be set with a minimum value (0.1).
Trigger levels for process high alarm are SP2 and SP-
AL.HY. Trigger level for process low alarm are
SP2+AL.HY and SP2.
Signal Conditioner DC Power Supply
Three types of isolated DC power supplies are available
to power an external transmitter or sensor. These are 20V
rated at 25mA, 12V rated at 40mA and 5V rated ar 80mA.
The DC voltage is delivered to the output 2 terminals by
selecting DCPS for OUT2 in set-up menu.
Limit Annunciator
If L.AN (Limit Annunciator) is selected for OUT2, output 2
will act as a Limit Annunciator. If the limit is or has been
reached and he REST key (or remote reset contacts) has
not been preset, then the limit annunciator output will be
energized and the OP2 indicator will be lit and remain
unchanged until the REST key or remote reset input is
applied.
RS-485 Communication
Using a PC for data communication is the most econom-
ic way. The signal is transmitted and received through the
SP2 = 200
AL.MD = NORM
AL.HY = 10.0
AL.FN = PV.H.A
17
There are two types of alarm modes that can be
selected, these are: normal alarm and latching alarm.
Normal Alarm: AL.MD = NORM
When a normal alarm is selected, the alarm output is
de-energized in the non-alarm condition and energized
in an alarm condition.
Latching Alarm: AL.MD = LTCH
If a latching alarm is selected, once the alarm output is
energized, it will remain unchanged even if the alarm
condition has been cleared, unless the power is shut
off or the RESET key (or remote reset button) is
pressed.
Failure Transfer: AL.FT - OFF or ON
In a case of Sensor Break or A-D Failure, the alarm
output will be on or off according to the selection of
AL.FT.
PC serial communication port (generally RS-232).
Since a standard PC does not support and RS-485
port, a network adapter (such as SNA10A, SNA10B)
has to be used to convert RS-485 to RS-232 when
RS-485 is required for data communication. Many RS-
485 units (up to 247 units) can be connected to one
RS-232 port. In other words, a PC with 4 comm ports
can communicate with 988 units. Ogden uses a
Universal MODBUS RTU MODE protocol to commu-
nicate via RS-485.
Set up
1. Select COMM for OUT2
2. Select an unequal address (AR) for those units
which are connected to the same port.
3. Set the Baud Rate (BAUD) and Parity Bit (PARI) so
that these values are accordant with PC set up
conditions.

Display Shift
In certain applications it is desirable to shift the con-
trollers indicated value from its actual value. This can be
easily accomplished with this control by using the dis-
play shift function. Cycle the control to the param-
eter by using the “Scroll”pushbutton. The number you
adjust here, either positive or negative, will be the
amount that the process value (PV) will be shifted from
the actual value. This amount will be the same across
the entire range of the control. Note the example stated
below.
The desired temperature at the part to be heated is 330
degrees F. In order to achieve that temperature, the
controlling value or the temperature at the sensor must
be 375 degrees F. Due to the design and position of the

placed any closer to the work.
Thermal gradients (different temperatures) are common
and necessary to an extent in any thermal system for
heat to be transferred from one point to another.
The difference between the two temperatures is 45
degrees F. You should input –45 as to subtract 45
degrees from the actual process value (PV). Cycle the
control back to the process value after making this
adjustment.
The display shift will alter the process value (PV) only.
The set point must be manually adjusted to 330.
